Fotodiox Umbrellas are designed to be used with any tungsten or flash light source. The umbrellas will soften, amplify, and ease the light output on the subject. Umbrellas with a white interior will soften and wane light more than an umbrella with a silver lining. This white umbrella without a black backing may also be used as a makeshift softbox, although the use of the light will not be as efficient as softbox. This umbrella is made of diffusive nylon fabric and easy to use in tight spaces. It has a minimum light reduction.
